System Requirements

At this time, we strongly recommend against using MATLAB R2008b on Unix-based systems. There are several unresolved issues with MATLAB R2008b that may prevent FOCUS from running.

Installation Instructions

Note to Windows users: Please make sure you have the appropriate Microsoft Visual C++ 2008 SP1 Redistributable Package (x86 or x64) installed for you computer, as these MEX files have been compiled using Visual Studio 2008.

Download the appropriate file — note that older versions of FOCUS will work in newer
versions of MATLAB, e.g. FOCUS for MATLAB R2010a will work in MATLAB R2010b.
